Some physical and chemical characteristics of Turkey oak seed oil (Quercus cerris L)

Abstract

The results obtained from the investigations on oil extracted from Turkey oak seed (Quercus cerris L) are shown in this paper. Using standard JUS ISO methods, some physical and chemical parameters wich characterize oil quality were determined in the extracted oil. The values obtained are approximately equal to ones for oils of similar composition. The composition of fatty acids was determined using GLC method and the most represented of them, oleinic linolic and palmitic acids made 94,89 % of the total fatty acids. The content ofunsatu-rated and saturated fatty acids was 79,34 % and 20,66 % respectively. Regarding the content of fatty acids, Turkey oak seed oil is the most similar to avocado and peanut oil. Turkey oak seed oil is very interesting for the possible use in cosmetic and pharmaceutical industry.

U radu su prikazani rezultati ispitivanja ulja ekstrahovanog iz semena cera (Quercus cerris L). U ekstrahovanom ulju su standardnim JUS ISO metodama određeni neki fizičko-hemijski parametri koji karakterišu kvalitet ulja. Utvrđene vrednosti su približno iste vrednostima ulja sličnog sastava. Metodom GLC je određen sastav masnih kiselina, od kojih najzastupljenije oleinska, linolna i palmitinska čine 94,89 % ukupnih masnih kiselina. Sadržaj nezasićenih masnih kiselina je 79,34 %, a zasićenih 20,66 %. U pogledu sastava masnih kiselina ulje semena cera je najsličnije avokadovom i ulju kikirikija. Ulje semena cera je interesantno sa aspekta moguće primene u kozmetičkoj i farmaceutskoj industriji.
